Application led Hay 9, 1808. Serial No. 431,882.

- citizen of the United States, residin at Chicago, in the county of Cook and tate of Illinois, have invented a certain new and useful Improvement in Paper-Interleaving Machines, of which the following is a speeliication.

This invention relates to paper interleaving machines and is an improved mechanism for performing the folding and packing operations which are performed by similar mechanism in United States Patent No. 867,159', issued September 24, 1907 to Herman I. Nager as the assignee of Herman Sauter.

The object of this invention is to provide a new mechanism for taking cut an' creased cigarette or toilet paper as it comes from a cutting and creasing mechanism and folding and packing .the same into a pile of interleaved paper. i

The invention consists in a chute for tho paper combined with a set of packing fingers movable in novel paths which assist in placing the pa er in proper position for packing and theno the desired packing, this with and without the added combination of latches for holding the paper in packed osition while the packing fingers with raw from contact with the paper.

The invention more in detail consists in novel mechanism for moving the lingers so v that it may successfully perform the opera- `mechanism for, moving the packing fingers,

tion in the manner above suggested and in other details of construction which will be' F ig. 6 is a lan view on approximately the line 6-6of ig 1, the chute not being shown y in section. Fi s. 7, 8 and 9 are sectional detail views on t e line A A of Fig. showing the parts in varioupbsitions which they'` assume during the operation of the machine.i

Fig. 10 is a sectional detail ,view showing the .hereafter described. The 'paper 27 is into and out of the chute. Figs. 11 and 12 are enlarged detail views showing different positions of the paper and (packing fin ers.

The machine is mounte upon a ta le 15 supported u n suitable legs or standards 16. From t is table at opposite ends rise end frame members 18 on which is mounted mechanism for cutting and creasing paper,

in this instance being the mechanism of saidA prior patent. This mechanism broadly speaking comprises four shafts 2() and 21 carrying rollers 2 3 equipped with cutting and perforating knives 24 and fingers 25 operating to deliver strips of paper 27 in the form Vof combined cut and creased paper at the oint 30 said paper then being as fully set orth in said prior patent ready t0 be folded in zig zag form within the chute r1- marily obtained from rol1s(not shovgvn) mounted on the upper or cut away portions of the angular u rights. 31. Through the table 15 is out a re atively elongated opening or slot having the sides 34 and ends 35.

Centrally located within this opening is a` chute' or passageway 38 into which the aper fed down to position 30 by the cutting and,

creasin mechanism is adapted to pass throng opening 40 between 'guardplates 41. The chute is rigidly mounted on the table by stub shafts 43 on the chute entering the castin s 44 secured to the table 15 by any suitable means.

.Briefly summarizing the foregoing it.will

be seen that the chute proJects ,upward through the table adjacent to the 'polnt 30. As the remaining part or parts of the machine are duplicated (but reversed) on each side of the chute a description of those on one side will be suiiicient. Upon each .shaft 20, to which power is communicated from flywheel 46 by gearing .'47 or any suitable means, is a sprocket wheel 49 over which passes a chain 50 engaging a pinion 51 mounted u on a sha t 52 journaled low down in t e end frames. This s rocket chain is kept at pro4 er tension by tilde idle tension wheel 53 ajustably mounted by means of theblock 54 and the bolt or pin 55 passing through elongated slot 56 in said lock 54. The rult of this construction is that power iny each shaftQO is transmitted to `Ythe adjacent shaft -52 from which it follows that as the shats20 control and regupaper is delivered at the point 30 as hereafter described each shaft 52 rotates at a fixed rate of speed with reference to the speed of delivery of said cut and creased paper at and past the point 30.

As shown in F ig. 6 the chute is very much longer in proportion to its width than is the chuteof the above mentioned prior patent, this so that relatively wide paper may be folded into the chute and then after removal from the chute be cut crosswise into a plurality of piles of paper which are ultimately broken up into a plurality of small This construction reduces the number of machines reuire to fold and pack a given quantity of nished product packages. In order that the machine may fold wide pa er as described a great many of the pac ring arts are duplicated along the length of the c ute, with the result that the drawings make the machine appear much more complicated than it really is.H The construction will be readily understood by the description, in gelneral, of only one of these parts on agiven s1 e.

Late/ies cmd latch operating mechanism.- Between each shaft 52 and the adjacent wall of the chute 38 is a small shaft 58 on which is rigidly mounted one or more upright levers 59 at the upper end of which is a pivotal bearing 60 on which is pivotally mounted a horizontal latch member G1 of such a length that its point 62 is adapted to alternately enter and be wholly withdrawn from the adjacent inner wall of the chute in the same manner that corresponding latches enter the walls of the chute shown in said prior patent. In order to hold these latches in a relatively fixed position and in contact with the up er surfaces of slots in the wall 38 throug which the point 62 passes .in entering and withdrawin from the chute, a coiled spring 64 is provlded attached to the end of the latch member 61 and the lever 59-as shown. The point 62 of the latch 61 is normall spring pressed inside the chute by the coi ed s ring 66 attached at 67 to the lever 68 an to the adjacent edge 34 of the opening in the table. Where more than one latch 61 is used they are as shown spaced some little distance apart along the chute. The distance to which each latch point 62 enters the chute is limited by stop 69 rigidly connected b any suitable means to the lever 70 carried y the shaft 58. In'other words the s ring 66 normally forces the point 62 of the atch 61, as far mto the packages or bundles. greatlv chute as the stop 69 will allow it to go.

Pivotally connected to the lever 70 at 71 is a horizontal rod 72 havin on its outer end a hook 73 adapted to cate upon in or post 74 rigidly mounted upon the ta le asy shown at a pointo'utside the shaftl52. Upon this shaift 52 is mounted a compound cam 76 having a tooth 77 adapted to engage tue underside 78 of the rod 72 and, as the cam rotates, lift said rod 72 oli'I from the post 74 upon which the rod has previously been hooked as is shown at the right of Fig. 7 and at the left of Fig. 8. This cam also carries a block 8O (best seen in Fig. 5) adapted to engage a dependin lug 81 upon the adjacent bar 72 and as t e cam is rotated, move the bar, contrary to the action of the spring 66 into the latched position just referred to. Each block 80 and the teeth 77 are so shaped and located that when the lhook 73 is over the end of post 74 the oints y 62 of connected latches are held entire y out of the chute for a suiicient length of time so that paper foldin mechanism, to be hereafter described, woring adjacent tothe particular latch (or latches) may force `the freshly folded pa er down below the plane of the latch 61 a ter which the member 77 engages rod 72 and nnhooks it from post 7 4, upon which the spring 66 instantly throws the latch or latches 61 into the chute over the freshly folded paper so that the folding mechanism may withdraw without the new fold in the paper being released and thereby spoiled. The cams 76 on opposite sides of the machine are so located with reference to each other that these operations take place alternately on opposite sides of the chute exactlv as in said prior patent. F oldz'ng mechansm-Vertically slidably mounted in any` suitable guides upon the upper ortions of the walls of the chute are two ro s or bars 7 9*iL each carryig at itsupper end a head 80"--81t provided with an elongated parallel sided slot 82. Adjacent to each head which in this particular machine is longer than the others is a guide rod 83 made in the particular case shown as one side of the slot.

Runnin through the slot 82 in the head 80* locate on a lven side of the machine is a rod 85 on whic is rigidly mounted a plurality of packing or folding fingers 86 adapted to enter the walls of the chute through 'notches 87.' The notches for successive fingers 86 are staggered with or placed between the latches 61 heretofore described. Rigidly attached to each rod 85 is one or more arms 89 (best seen in Fig. 2) having thereon an angular portion 90 on whchare fingers 91 and.92 passing on opposite sides of the rod 83 with thc result that as the rod 85 with` attached parts is moved backward ism (Fig. 10). 0n the adjacent shaft 52 is an eccentric 95 inclosed by an eccentric band 96 attached to a connecting rod 97 which is in turn pivotally connected at 98- to a vertical lever 100, pivoted at 101 upon a lug 102 mounted upon one side of the chute. In the upper portion of lever 100 is an elongated sldt 104 throu'h which the adjacent rod 85 passes fromwhich it is seen the rod S5 may be raised and lowered a distance equal to the length of. this slot Without interfering with the reciprocating horizontal motion given to it hy the `lever 100 acting under the influence of power from shaft 52. 'The rod 85 is raised and lowered by the following mechanism; the bars 79El are normally spring urged upwards by springs 106 which are resisted by a'horizontal lever 107 adjustably ivoted at`108 engaging the bar 79 on the p ates or lugs 110, and a cam 112 also mounted upon the shaft 52. This cam has a face 113 so shaped that when it is in contact with the adjacent lever 107 the bar 79l1 connected therewith will be held in depressed position and it has another face 113a so shaped that when it is in contact with lever 107 lthe attached bars 79 will move to highest position under the action of the spring 106. As the shaft 52 rotates cam 112 s1multaneously with cam 76 it follows that this mechanism just described causes the rod 85 to travel up and down in slot 104 during a portion of the reciprocation of lever 100 and to remain at rest in lowered position durin the remainder of the movement of the ever, with the result that the real path of travel of the center of rod 85 is substantially that of the dotted paths 114 and 115 shown in Fig. 10; the direction of' travel of the rods on opposite sides of the machine being as indicated by the arrow heads viz. clockwise at the left and counter clockwise direction at the right.

The cams .and other parts on o osite sides of the machine are so located wit reference to each other that the rods 85 on op posite sides always occupiy exactly opposite or opposing portions o their respective paths 114 and 115. As all of the parts attached to the rod 85 move absolutely in unison and parallelto it the packing fingers 86 move in paths parallel to paths 114 and 115, that is to say assuming that the mechanism described has elevated them as hi h as possible and the are withdrawn as ar as possible from t 1e chute, they move into the chute horizontally for some distance and then gradually descend across the chute to a point at which they depress the paper (as shown on the left` hand side of Fig. 8) sufiiciently 4so that it is ossible for the latch members 61 which ave previously been withdrawn from the chute to spring in over the freshly pressed paper after which the fingers 86 are horizontall withdrawn from the chute in a horizontal ine corresponding to the bases of the paths 114: and 115 and finally returned by any suitable path to original position. It may be clearly and fully stated here that the path of travel in returning from the lower position to the upper position is entirely immaterial and is therefore represented by, vertical straight lines in paths 114 and 115 although the actual path of travel ma in this articular machine be slightly ifi'erent. t is to be noted that the lower or packing faces of the fingers 86 are not horizontal but are inclined at a slight angle to the horizontal thereby readily assisting the packing and pressing down of the paper in the manner described more satisfactorily than perfectly horizontal fingers would Work.

Figs. 7, S, 9, 11 and 12 illustrate the successive positions of the packing fingers and the paper. Fig. 12 is an en arged detail view of the fingers and paper in the same position as Fig. 8. The operation of the device will be most clearly understood by giving to the cut and crease in the incoming pa r, which is at positiony 30 of Fig. 7 hereto ore described a numeral'fas 120 and giving it the same numeral in the other figures so long as it is en aged by the left hand packing fingers an then when the right hand packing lingers begin to work on it giving it the numeral.121. With this understanding the operation of the machine will be clearly understood by stating that the left hand fingersfirst cause joint 120 to successively assume the positions of Figs. 7, 11, 8 or 12, and 9 at which time the right packing fingers treat this same joint now numbered as 121 as shown and successively move it to positions of Figs. 9, 7, 11 and 8 or 12. It is of course understood that While the right hand fingers and other parts have been operating on the joint 121 the left hand fingers have been folding in another or second succeeding joint 120 in exactly the same wa as the first one was. It must also be un erstood that the right hand fingers fold in right hand angles or joints 122 on the left hand side of the chute exactly as left 'hand fingers foldrin joints 120 and hold joints 122, now numbeledv 123.

Particular attention is called to Figs. 11 and 12 which show the manner in which the *ends 126 of the packing fingers 86 engage the end portion 127 of the incoming piece of paper and force it into place in the fold. The n'iovements of the parts are so timed that the ends of the fin ers engage the incoming paper about hal ,an inch above its end and stay in contact with some part of the end position until it is in proper interfolded osition as described.

' lt wi l be particularly noticed that owing to the angularityof the packing fingers 86 the paper is well packed at the edges adjacent to the points where the latches 61 are snapped in without undul at the same time pressing down the portion of the paper which is in the center and the portion of the paper which is toward the opposite side of the chute thereby not interfering with the natural incoming motions of the paper, this being quite important because of the fragile character of the paper packed.
